By grouping several objects together, you can format multiple objects at once rather than formatting each object individually.
Select all the objects you want to group together.
Press and hold down Shift as you select multiple objects.
Click the Layout tab on the ribbon.
You can also click the Format tab on the ribbon — the Arrange group on either tab includes the Group button.
Click the Group button.
The selected objects are grouped together.
Now that the objects are grouped, you can apply effects to all three objects at once and move the grouped objects around the document together.
You can also right-click selected items and select Group from the contextual menu to group objects.
If you need to apply some formatting to just a single object in the group, or move something around within the group, first select the group, then click the object you want to format within the group. Just that object is selected, but it remains part of the group.
